` VEHICLE-GEAR.

Beit'knownthat I, FRANK E. WiLooX, a citizen of' the United States, residing aty Mechanicsburg, in the county of Cumberland and State of Pennsylvania, have invented new and useful Improvements in Vehicle- Gears, of which the following is a specification.

The object of my invention is to simplify the ordinary vehicle-gear, wherein a separate metallic head-block plate and wooden head-block are used, by substituting for the said plate and block a cored-out malleable iron or steel element which shall be adapted to perform the functions of the plate and head-block and which, moreover, shall be of light Weight,' of ample strength, and not more costly lthan the two elements usually em lo ed.

it this end in view my invention consists in a metallic head-block, cored out to secure'lightness of weight, provided at the top surface With a concave seat for a spring, seats at the lower surface and adjacent the ends for the reception of the ends of the upper fifth-wheel member, anda seat at the lower surface and at the center for receiving the v Yend of a single reach-iron.

. king-bolt.

It further consists in certain novelties of construction and combinations of parts hereinafter set forth and claimed.

Figure 1 is a perspective view of the gear with the parts assembled. Fig. 2 is a front view ofthe gear in elevation, par/t of the metallic head-block being in vertical section. Fig. 3 is a vertical section on a line with the Fig. 4 shows the end of the reach-iron.'

Referring` to the several figures, the numeral 1 designates the axle 3 2, the axle-bed; 3, a four-pronged king-bolt axle-clip; 4, the threaded front prongs of the clip; 5, the threaded rear prongs; 6, a perforatedy lug integral with and at the rear of the clip; 7, a tapering projection at the top of the lug to engage a seat in the lower surface of the reach-iron; 8, the clip-yoke having five holes therethrough, four for the prongs of the clip and one for the king-bolt; 9, nuts upon the rongs; 10, a brace and brace-head; 11, the

ower circle of the fifth-wheel; 12, the clips andfokes by which the lower circle is secure to' the axle and bed; 13, the reach; 14, the reach-iron; 15,' a seat in the-iron to receive the projecting part 7 of the axle-clip with which it interlocks; 16, a concave seat lSpecification of Letters Patent.

for the head-block; 17, a hole atv the eX- treme end to receive the prong of a clip; 18, a holefor .the passage of the king-bolt; 19, two holes to receive the prongs of a clip; 20, the s rings; 21, a three-pronged cli embracing t e springs and metallic headwith its prongs passed through the holes in the end of the reach-iron; 22, nuts upon the threaded ends of the prongs; 23,'the upper Vfifth-wheel circle or member; v24, seats a cent the ends of the circle; 25, the cored metallic head-block; 26, a concave seat for a spring at the upper surface of the head-block; 27, seats at the lower surface and adjacent the ends to receive the ends of the upper fifth-wheel circle with which ends the headblock interlocks; 28, a block of yielding material, as wood, seated in the metallic head-block and perforated to receive a bolt; 29, a bolt uniting the head-block and the upper fifth-wheel member, which latter has a hole therethrough for the passage of the bolt, the head being countersunk, as shown; 30, a seat at the lower surface of the metallic head-block for the reception of the end of the reach-iron, with which it interlocks; 31, the headed king-bolt passed through the reach, reach-iron, lug of the four-pronged clip, the axle-yoke, and the brace-head, and 32 is the nut on the end of the king-bolt.

It will be observed that with the construction shown no head-block plate is necessary, as the lower part of the metallic head-block performs the function of such a plate. The head-block may be fashioned .to any desirable shape in outline and be provided with strengthening-ribs, though such ribs are not shown by the example illustrated. The to wall at the spring-seat and the bottom wal j and 34, and the number of these openings and their disposition may be arranged and varied at the will of the manufacturer. However, the webs 35 and 36 should be resent where the'ends of the upper fifth-whee member and the reach-iron interlockfand n IOO lock with the head-block. Projections 37 IIO cle-gear provided with three seats at its lower su l ace for the end of the reach-iron andthe ends of the upper fifth-wheel member.

3. A hollow metallic head-block for a vehicle-gear provided with a concave seat for a spring at its upper surface and with a seat at its lower surface midway of the ends for the end of a reach-iron.

4. The combination with a, hollow metallicY hea "block having a" seat at its lower surface midway of the end;A of a perforated reach-iron i'illlterlocking with said s'ea't, aL spring,A and a c i g'. Tliecombiination with a hollow metallic head-block having a seat at its lower surface, of ai perforated reacheiron interlocking with said seat, a spring, a clip, an axle-clip with a surface, of a reach-iron, the upper member of a ifth-wheel, a spring, a clip, and means for securing the ends of the fifth-wheel member to the head-block; said reach-iron and the ends of the fifth-wheel interlocking with the head-block.

In' testimony whereof I alia m'y signature in presence of two'witne'sses.
